Everything I've read says the 6750 smokes my old 4650.

Now that I've installed said 6750, I'm finding that to be entirely untrue. It runs the same, if not worse, than my 4650.

Was I wrong to expect a performance increase?

Could it be I need to roll back to older drivers because the newer ones are terrible?

Halp.
 
Hearing from others that it's a possible BIOS issue...

Well, there's a definite BIOS issue, just not sure if it's the cause of the poor performance or not.

So I'm going to try that and report back... If no change, this pig is going back and I'm putting the cash back in my pocket because, well, not a lot of point if I'm not going to gain anything.
 
I wouldn't say the 6750 would beat your 4650 to too much. It should be equivalent to a 4850. However, you should have seen a definite performance increase. I would un install and reinstall all your drivers. What brand is the card?
 
Not to mention, what motherboard are you using and what BIOS error were they talking about?

See, 4850 levels would be fine. It'd be something at least.

4650 was XFX, 6750 is XFX.

I went for the 6750 thinking it'd do something noticeable... If I'd been wise enough to ask you lot I wouldn't have bit. If I don't get what I need out of it after a round of troubleshooting and flashing the BIOS, it's going back. And I'm going hunting for another pair of 8800GTs or something.

Kinda sad, really... I bought the 4650 after my old 8800s died on me because this mobo doesn't have integrated graphics and I needed something to keep it going and didn't have my old FX5200 around to chuck in a PCI slot. Expected a performance hit and got one (though not quite as big as people were telling me it would be), dealt with it until now.

I'm using an Asus M2N-SLi with the as-shipped BIOS.

It doesn't boot properly with 5xxx or newer ATi cards (cycles a ton before it actually posts), and it may also have performance issues with them...

Actually... Someone find me something that will actually run properly.

M2N-SLi + AMD 5000+ BE + 4x1gb OCZ RAM (dunno exacts).

Edit: Flashed BIOS, it now boots properly but no change in performance.

Miserable card is miserable. NEXT!

Have you tried checking the clock settings? It should be 700Mhz on the core and 1000 mhz on the memory. You could run benchmarks too, just to see if its the game or the card.
 
It was at 700/1000.

Now it's at 850/1200. Seems like the games I tested initially (APB Reloaded and Drift City) simply don't like me at all because Skyrim runs better on higher settings, ditto for Borderlands... And I've nearly run out of games to test.

That's 6770 Specs :)

I know. ;) Friend of mine recently picked up a 5770 and it's been driving him mental because he got better FPS with a GT430 on a certain track in Drift City... And I'm seeing little improvement there over my 4650. BUT! FPS is better everywhere else for both of us.

I think its a driver problem. Uninstall everything, then completely reinstall every driver. Make sure you install ONLY AMD drivers.

Could be, and I have done... Though maybe I should shut it down, stick the 4650 in, uninstall it, then swing the 6750 back in? I dunno lol. I mostly kinda know what I'm doing but not really if you get me.

And on the subject of drivers, I hear a lot of stuff about Catalyst getting progressively worse from a performance standpoint, and from what I saw at one point it's true. Went from one Windows install with newer drivers to an older install, got better framerates.

So, what's the "best" driver set I can actually use with this card?
 
The best driver set are the current ones. I believe its release 11.12? What I would reccomend is to uninstall all the drivers with the 6750 in until Windows uses its own driver. It should give you a WEI score of 1.0 and only allow you the crappy Windows scheme, not the glass one. Once you have achieved that, you can be glad to know that that is how your PC should be when you do a fresh install of Windows 7. Once you have achieved that and admired your hard work, you can go ahead and install the AMD driver.
 
And it does since I own an HD 6770 myself. When I first used my HD 6770 with minecraft I gotten 60-100fps. With some other adjustments for performance in the video settings for minecraft I've gained a lot more. When I turned "Advanced OpenGL" off, in the video settings in minecraft, my average fps was over 100.
 
Smooth Lighting is off, Graphics is Fast, Advanced OpenGL is off, and Performance is Max FPS. Lets be honest here, minecraft does not need to be pretty!
 
Then that is what you would call smooth video. If you are getting that then it's good enough. Main differance from my system to yours is that My CPU is different. My CPU is the FX-8120 where yours is the FX-4100. Minecraft also only uses a single core of your CPU. So when you get faster fps from a different game means it's using more than one core to run itself. You should also know that Microsoft and AMD is releasing an windows update patch in Q1 of 2012 to update windows to use the FX processors more properly and generally increase performance.
 
It only does in a certain extent. If you were using Intel graphics then you would have trouble keeping fps up to the same level when you use the same option that are used for better graphics cards such as an HD 6770.
 
I use a CRT HDTV currently for my computer but I've found this article as a good read. So from what I read so far is that 60fps is normal and it is smooth.
